In `@source/end-user-guide/collaborate/react-with-emojis-gifs.rst`:
- Line 77: The constraint sentence about animated GIF emojis is too vague and
does not specify the actual frame limit. In the sentence that currently reads
"Mattermost limits the number of frames allowed in animated GIF emojis," replace
this with precise constraint information that explicitly states the 32-frame
limit. Ensure the revised text clearly communicates to readers the exact
limitation value so they understand what "limited" means (for example, "Animated
GIF emojis are limited to 32 frames" or present it as a separate note for better
scannability).
